Damper device

A damper device, comprising:

• a first rotor;
• a second rotor rotatable relative to the first rotor;
• a plurality of elastic members circumferentially aligned, the plurality of elastic members configured to elastically couple the first rotor and the second rotor in a rotational direction;
• an intermediate member disposed axially between the first rotor and the second rotor so as to be rotatable relative to the first rotor and the second rotor;
• a hysteresis generating mechanism disposed axially between the first rotor and the second rotor, the hysteresis generating mechanism configured to generate a hysteresis torque in relative rotation between the first rotor and the second rotor;
• a first spacer;
• and
• a second spacer,
• wherein the intermediate member includes an annular portion and a support portion,
• the annular portion is provided radially outside the plurality of elastic members,
• the support portion protrudes radially inward from the annular portion, the support portion disposed between at least circumferentially adjacent two of the plurality of elastic members, the support portion configured to actuate the at least circumferentially adjacent two of the plurality of elastic members in series,
• the hysteresis generating mechanism includes a friction member disposed axially between the first rotor and the second rotor, the friction member making contact at a first axially lateral surface thereof with the first rotor, the friction member making contact at a second axially lateral surface thereof with the second rotor,
• the first rotor includes a first input plate and a second input plate, the first and second input plates each having a disc shape, the first and second input plates axially opposed to each other, the first and second input plates fixed to each other,
• the second rotor includes a flange disposed axially between the first input plate and the second input plate,
• the intermediate member includes
• a first intermediate plate disposed axially between the first input plate and the flange, and
• a second intermediate plate disposed axially between the second input plate and the flange, the second intermediate plate fixed to the first intermediate plate so as to be immovable with respect thereto in both axial and rotational directions,
• the first intermediate plate includes a first annular portion and a first support portion, the first annular portion forming part of the annular portion, the first annular portion disposed radially outside the plurality of elastic members, the first support portion forming part of the support portion, the first support portion protruding radially inward from the first annular portion,
• the second intermediate plate includes a second annular portion and a second support portion, the second annular portion forming part of the annular portion, the second annular portion disposed radially outside the plurality of elastic members, the second support portion forming part of the support portion, the second support portion protruding radially inward from the second annular portion,
• the first spacer is disposed axially between the first annular portion of the first intermediate plate and an outer peripheral part of the flange, and
• the second spacer is disposed axially between the second annular portion of the second intermediate plate and the outer peripheral part of the flange.
